Any EZ Go Master Mechanics Robin Engine Here?

The ignition on these isn't magic, the only neat thing it does is have the ability to use the starter as a generator, and spin it two ways. Check your limit switches, also do some diode tests, your diagram doesn't show them but there are a few in the system. https://www.golfcartsforum.com/foru...go-workhorse-with-350-robins-engine#post43013 has a bit better diagram. They're all on the starter/charging side of the circuit, as a sanity check if the reverse beeper sounds when you're in reverse they should be good.

 

Always think it’s about you, don’t ya James Taylor?

 

Reported.

 

Thank you, I would of never figured that out. Will check tonight.

 

For yourself right?

 

You’re not even the asshole that lit the fart lately in here... let alone blown shit up! Puns definitely intended!

 

Try different spark plugs ?

Does the motor run on starting fluid spray ?

If it has "weak" spark and you havent messed up it should still run on starting fluid spray.

What kind of voltage do you have at the plug leads ?

 

No one ever called me insufferable. And lived.

 

Yes, I'm on my 2nd set of plugs. First set was part of a "Tune Up" package from Amazon and didn't trust them.

I did try the juice and it didn't even try to cough.

Have not checked voltage at the plug leads. You have a range I should be looking for? I assume plug to ground? AC voltage?

 

I actually did a little bit of sluthing on this engine. Based on the parts he already has replaced, I'm going to go with a bad solenoid. Probably really high resistance across the contacts, causing a voltage drop, so the ignitor doesn't want to fire.

To bad I'm on ignore so numb-nuts won't see this. Lol.

 

I think pulsar I ordered from Amazon was a scam. Only measures 200 ohms. The pulsar genuine from EZ GO is a tad over 500 ohms.

The original one which most likely got damage from power washing measures 20 ohms.

Won’t be able to install tonight. Have a school board meeting. I’m really hoping this is it.

 

You need to find a Master Mechanic.

 

Someone else mentioned checking all the grounds. I found this the be an issue on mine. I also found the key switch on mine can catch in between off and on, like Accessory on a car. It would flood out if you didn’t realize it was in the middle because it would still crank but not spark.

SOLVED!!!!!

As I thought I had damaged a component during the power wash. The Pulsar (pick up) was reading less than 30 ohms. We ordered a brand new one from Amazon and that's when our journey down the rabbit hole started. Long story short the Amazon pulsar does not meet EZ GO Specifications. Found out a couple days ago it should read over 500 ohms. Out of the box it was only reading 200 ohms. Because we assumed the pulsar was good we continued on the troubleshooting tree changing out Ignition coil, plugs, plug wires, voltage regulator, CDI.


After we sourced the proper pulsar we ohmed out and it did indeed read 500 ohms. Unfortunately slight modifications were needed to the bracket as the mounting holes would not line up.



After installing the pulsar the cart still refused to start and again the same issue of no spark. So I started going backwards thinking that perhaps I had more bad parts from Amazon. I put the system back to as found with the original parts besides the plugs and plug wires. Last part I removed was the voltage regulator.

Whelp, when you mess up you need to own it. And yes I did eff up. My attention to detail was lacking and the new voltage regulator was installed in the wrong orientation. The three wires were crushed to ground.



We now have a running cart! Thanks for all the help!

Lol so you didn’t need a master mechanic. You just didn’t need to check the cheapest/easiest source of Chinese junk.

 

I hope he doesn't work on his kid's bikes.

 

Well, it was certainly a kick in the balls.

If the manual had stated to check for 500 ohms on the Pulsar this adventure would of been over. That information did come from a "Master Mechanic" via a EZ GO FB group.

Unfortunately this series of EZ GO Cart is no longer having parts manufactured by the factory. That Pulsar I finally located took almost a whole day to source at a very significant cost increase from the Amazon "junk".

I've been racing / buying Chinese "Junk" for the past five years. This is the first blatant issue I've had with a Chinese replacement part.

Lesson learned, and now I feel confident taking on more of these Robin Engine carts if found on the cheap!

 

Was it really the pulser, or the regulator shorting out?

 

Yes, the initial issue was damaging the pulsar when I power washed the engine. It was reading less than 20 ohms.
